Orange is intensifying its efforts in quantum technologies as part of a long-term strategy to safeguard its networks and develop next-generation secure communications infrastructure. With quantum computing poised to challenge today’s cryptographic systems, Orange is investing in post-quantum cryptography (PQC), quantum key distribution (QKD), and collaborative research to address the emerging cybersecurity threats posed by quantum capabilities.
The company began its quantum initiative in 2017, becoming the first telecom operator in France to test QKD over a live fiber network in the Paris region. Orange is now a core participant in major European and national quantum initiatives including EuroQCI, FranceQCI, and Prometheus, all of which aim to build secure quantum communication systems and infrastructure. The goal is to establish quantum-secure links that can withstand future threats from quantum decryption—particularly those anticipated by “store now, decrypt later” strategies already in use by advanced threat actors.
Orange’s roadmap combines short-term upgrades to encryption systems with long-term development of quantum networks. QKD leverages quantum mechanics to generate and distribute cryptographic keys with physical guarantees against interception. Meanwhile, the company is advancing PQC algorithms to withstand brute-force quantum attacks. Both tracks aim to ensure data confidentiality, especially as quantum computers mature and begin to challenge RSA and ECC-based systems, which could become vulnerable as early as 2030.
